Default how do I test my injectors

I have a 1995 d16z6 with a p28 ecu in a 91 hatch, every thing is wired. I got the car to start for a second, now im not getting injector pulse. I put a screw driver from the injector to my ear and didnt hear anything. The fuel pump is working and i can hear fuel going through the fuel rail. What should I check?

To make sure it is a fuel issue try starting fluid and see if you can get the car to run that way.

Injector pulses? how do you know you even have injector pulses? Did you check using noids lights? Injector pulses are control by the computer. It's power and ground is thru the computer.

when you removed the resistor box, did you connect all the wires together that went to it?
